ESP PSD2 Installation Instructions

OPTICAL SMOKE DETECTOR

TYPE PSD-2

INSTALLATION MANUAL 18020608

ATTENTION: This manual is subject to change without notice!

Read carefully this installation instructions before installing the device!

GENERAL DESCRIPTION:

The detector PSD-2 is compatible with any conventional Fire Panel with low fire alarm
threshold between 10mA and 15mA.

The optical smoke fire detector PSD-2 is used with fire base B24RD - Standard
base with Schottky diode and increased alarm state current.

INSTALLATION

1. Choose the proper place for installation of the fire detector. Refer to the given

installation instructions.

Note: Do not install the detector near sources of steam, condensation or smoke,

e.g. from cigarettes.

2. If you want to “lock” the detector to the base remove the little “tooth” (with the
triangle shape) and break the plastic key off the base. Keep the plastic key in safe place
to be able to open the detector later.

3. Mount the fire base on the ceiling of the protected premises using fixings according
the mounting surface.

4. Connect the detector base to the fire panel using the wiring diagram.

ATTENTION: Disconnect the line power before installing the detector!

5. Insert the detector into the base and rotate clockwise until it drops into place.

Continue to rotate the detector until it locks to the base - a click is heard.

6. If the detector has been locked to the base, when open it for a service schedule
maintenance and cleaning you have to use the plastic key. Light press with the plastic
key into the base opening and at the same time rotate the detector head counter­clockwise.

ATTENTION: To clean the wire mesh you have to remove the detector’s PCB and
then carefully to disassemble the smoke chamber from it. Clean the wire mesh
and mount the chamber back on the PCB as observe the arrows - they have to
coincide, then slightly press the chamber to the detector’s PCB. Next you have
to mount the PCB back to detector’s plastic body. Find the color dot sticker on
the PCB and orientate it to the mark on the plastic body (visible from the
outside). The hole next to the color dot have to coincide with the pin on the
plastic body. Gently press downwards to fix the PCB in place.

TESTING THE DETECTOR
To test the detector use a smoke probe:

1. Apply power to the detector.

2. Wait for 30 sec.

3. Еxert influence on the fire detector by smoke generator (Dispenser) or another
device with aerosol simulator of smoke. Within 8 sec the fire detector will enter in fire
condition. Both LEDs will light up.

4. Power off the detector for 2sec minimum. After resetting the detector will enter in
duty mode and the LEDs will light off.

SERVICE MAINTENANCE

1. Inspection for visible physical damage - weekly.

2. Operational test in real conditions - monthly.

3. Check and clean dust contamination - six months.

4. Check and clean base and head contacts and connections - annually.
